Model primary content type for multipurpose internet mail extensions

摘要

The purpose of this memo is to propose an update to Internet RFC 2045 to include a new primary content-type to be known as 'model'. RFC 2045 (1) describes mechanisms for specifying and describing the format of Internet Message Bodies via content-type/subtype pairs. We believe that 'model' defines a fundamental type of content with unique presentational, hardware, and processing aspects. Various subtypes of this primary type are immediately anticipated but will be covered under separate documents.
